Virtual machines require virtual networks to communicate with other computers. After you install this role, you can create virtual machines and attach them to a virtual network.  One virtual network will be created for each network adapter you select. We recommend that you create at least one virtual network now for use with virtual machines. You can add, remove, and modify your virtual networks later by using the Virtual Network Manager.
